INSULATED HANDLE FOR HOT-WATER VESSELS.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed January 22, 1910. Serial No. 539,595.

To all whom it may concern:

Be it known that I, ALEXANDER MACBETI-I, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Insulated Han dlesfor Hot-Tater Vessels, of which the following is a specification.

This invention relates to certain new and useful improvements ininsulated handles for hot water vessels, and has for its object a handleof this type which will be completely insulated so as to be incapable ofbeing heated by the contents of the vessel.

Further objects of the invention are to provide an insulated handlewhich is simply and economically constructed, of great efliciency inuse, and presenting an ornamental and attractive appearance.

Further and other objects will be herein after set forth.

In the drawings, Figure 1 is a side elevation of a fragment of a tea,coffee or other hot water vessel, showing the handle applied inposition. Fig. 2 is a central longitudinal cross section of one of themembers of the handle. Fig. 3 is a view similar to Fig. 2, being anothermember of the handle. Fig. 4: is a section taken on a line H of Fig. 5.Fig. 5 is an elevation of one of the members of the handle, the samebeing partly broken away and in section, and Fig. 6 is a sectional Viewtaken on the line 66 of Fig. 3.

The tea, coffee or other hot water vessel is designated by the numeral 1in the drawings and has secured thereto the outwardlyextending arms 2which latter are depicted in the drawings as being of hollowconstruction.

The handle proper is designated by the reference numeral 3 and same isconnected to the outer ends of the arm 2, the present invention residingparticularly in the means for connecting the ends of handle 3 with theouter ends of the arms 2, and as each of the connecting means is similarin all material respects, but one of same will be particularlydescribed.

The arm 2 is formed with a seat 4 preferably by turning the outer endportion of the arm 2 inwardly in a manner illustrated in Fig. 3, and inthis seat a cylinder-like metal member I5 is secured by soldering or anyother approved means, member 5 projecting beyond the outer end of arm 2and being formed with a transverse perforation 6. The perforation oropening 6 has its walls lined with suitable insulating material such asivory, bone, wood or fibroid, the lining in the present instanceconsisting of a bushing 7 formed of the insulating material and securedin the opening 6 in any suitable manner.

The ends of the handle are pressed inwardly as at 8 and are formed withseats 9 in which are held blocks of insulating material 10. The outerend of the block 10 is preferably given a concave contour as shown. Eachend of the handle is further formed with a pair of opposite outwardlyextending cars 11 which are perforated as at 12.

The connecting member proper consists of a ball-like element 13 formedof insulating material and provided with opposite flattened portions 14and with diametrically opposed openings 15, one side of the ball beingcut away as at 16 to receive member 5. The ball may be hollow as shownin Fig. 3, or solid if preferred, and is formed on its periphery withoutwardly projecting teats 17, the function of which will now be setforth.

In assembling the parts member 5 is received in the interior of the ball13 being passed through the cut-out part 16, the openings 15 in the ball13 being brought to aline with the opening in the bushing 7, after whichthe ball 13 is placed between the ears 11 of handle 3 so that theregistering openings 15 and that of the bushing will register with theperforations 12 in ears 11, whereupon a retaining pin 18 is passedthrough all of the registerlng openings just noted to secure the partsin their respective position.

By inspection of Fig. 1 it will be observed that the teats 17 engagebetween the adjacent end portions of arm 2 and handle 3 and therebyprevent contact between such portions, assuring of perfect insulation atthese points.

It will be observed that by the above construction and relationship ofparts that complete and perfect insulation is obtained. Moreover thedevice is simple and economical in construction and can be readily andquickly assembled. None of the metallic parts are in actual contact witheach other, and consequently traveling of the heat from one part toanother is positively prevented. The insulating block 10 acts to contactwith the ball and thus further assures of a more thorough and completeinsulation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In combination with a vessel, an insulated handletherefor consisting of a handle groper, perforated ears carried by thehanle, an insulating block carried by the handle and located to the rearof said ears, an arm secured to the vessel, and having an outwardlyprojecting member carried thereby, said member being perforated andhaving the walls of the perforation lined with insulatingmaterial, ahollow ball having a cut-away part to receive said projectlng member ofthe arm, said ball being perforated and adapted to have the perforationregister with said opening of the projecting member of the arm, a teaton said ball projecting outwardly and adapted to engage between adjacentend portions of the arm and handle, and a retaining pin passed throughthe registering openings of the projecting member of the arm, of theball, and of the ears of the handle.

2. In combination with a vessel, an insulating handle thereforconsisting of a handle proper, an arm on the vessel formed with anoutwardly projecting member, a hollow insulating ball receiving saidprojecting member of the arm, means on the handle to embrace said ball,means for securing the handle, ball and projecting member of the armtogether, and means carried by the ball to engage between the adjacentend portions of the handle and arm, to prevent contact between same.

3. In combination with a vessel, an insulated handle therefor consistingof a handle proper formed with perforated ears, a block of insulatingmaterial carried by the handle proper and being arranged to the rear ofthe outer ends of said ears, an arm on the vessel formed with anoutwardly extending substantially cylindrical member, a hollow ballformed with an opening to receive said cylindrical member to allow thelatter to project on the interior of the ball, and a securing pinextending through said perforations of the ear and throu h openingsprovided therefor in said cylin lrical member and said hollow ball.

4. In combination with a vessel, an insulated handle therefor consistinof a handle proper having an insulating block, an arm on the vesselformed with an outwardly extending cylindrical member, a hollow ballformed with an opening to receive such cylindrical member and having itsportion diametrically opposite to said opening disposed in proximity tosaid block of insulating material, and means passed through the handleproper, the hollow ball and said cylindrical member to unite said parts.

5. I11 combination with a vessel, an insulated handle thereforconsisting of a handle proper, an arm on the vessel formed with anoutwardly extending cylindrical member, said member being formed with atransverse opening, a bushing of insulatin material lining said opening,a hollow ball of insulating material formed with an openim to receivesaid member, the latter extending loosely on the interior of the ball,and a retaining pin extending through the handle proper, said bushin ofinsulating material, and through the balI to connect sald parts.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALEXANDER MAOBETH.
